Need a more help, because my program didn't see my TV.
I used this server often, but now can't see my D5500. I don't know how to fix it, because this program hasn't any settings.
Need a port number for communication for firewall and need any special settings what help to me. I have Win10 64-bit with latest updates.

What I checked:
- My PC and TV on same LAN and router.
- Windows Media can transfer video to TV.
- TV see internet too with cable.
- Reinstalled this program.
- Turn off and on Windows firewall

Just some take-it-or-leave-it thoughts:
-Is it absolutely needed to exit app on computer side? I mean: can't app detect if video had been stopped on TV side (either by user or when it reached the end) and exit itself in such case?
-I've got 2 TVs on LAN and I can launch only one movie on one TV at once (allow several instances?)
-Worth a tip on notification icon when mouse cursor left on? (e.g. "Playing movie_name on tv_name", instead of current "Play on TV")

Thanks for the comments. I'll add that notification, but you can see already what's being played in TV player, for example by pausing the player.

The app meant to be simple. Basically I wanted to play a file on TV by simply clicking on it. Didn't want to go through any complicated UI or to have to setup or maintain media library and scan folders for new files, like typical DLNA servers work. Hence the app asks just on startup which device to use and stays resident. It uses little resources, so I don't think it's a big problem for todays modern computers. It's not easy to detect TV player has finished, unless I implement full DLNA controller specification.

I know other DLNA white elephants and I've understood the principle of "simplest possible" (precisely what I like), that's why I suggested (not expected, it's up to you) only stuff that wouldn't make UI heavier
